High speed packet radio collapsed at 9.6 kbps because hams were no longer
able to hack modems into surplus land mobile radios. For the first time,
one needed full channel equalization and plug and pray no longer worked.
That was pretty much the end of packet radio circa mid 1990's. The only
thing that survived was APRS which is based on cheap land mobile radios, PIC
microcontrollers, and AX25/UI.

According to the TNC-X website, John Hansen claims to be working on a 9K6
modem but that was quite a few years back and nothing has been heard since.
I'd LOVE a 9K6+++ modem but they just don;t seem to be available.
I've looked at quite a few of the old designs that came out of German and
Slovenia back in the late 90's and early 2K's. They are either no longer
available, require an SCC card to provide clocks etc, have no driver support
any more or require firmware which is unavailable.
Whilst the soundcard road is somewhat acceptable, a hardware modem can't be
beat..

A few notes:
1) There is a TNC board for the RPi: http://tnc-x.com/TNCPi.htm and it
supports stacking multiple TNCs on a single RPi. It's a pretty elegant
solution.
2) The RPi has UART pins on the I/O connector. All you need is a RS232 to
LVCMOS level converter. The only disadvantage to that is that you can only
connect a single TNC unless you go to NETROM firmware on the TNCs.
3) Using USB<->RS232 converters should work but do yourself a favor and
avoid any adapter that is based on the Prolific chipset. The number of fake
Prolific devices on the market is unreal and their drivers are very suspect.
Use FTDI based devices as they have done a good job of protecting their IP
and maintaining a stable driver set for Windows and Linux.

Hi there
Is there a way to have a Packet Node with Pi (or any other small size
solution that will not require a PC) ?
If yes How do I connect TNC (serial port) to PI is the Pi support USB
to serial external interface (like the profilic ones) ?
Or (preferred) something can be done to do the TNC on Sound card (can
be an External sound card that connect to the USB of the PI)
Please Advice
Thanks Forward

Please do not perform any coninuous monitoring or other probing of any other networks than your own
without the explicit desire and consent of the operators of the other network.
We are blacklisting all sources of unwanted monitoring and probing traffic like research scanners,
shodan.io etc etc and I regularly send opt-out messages to those. Still we get over 1 megabit/s
of such crap all day.

I have 4 snapshots of the BGP routed subnet situation here, and this entry
is present in all of them. It apparently is not a recent change.

Tom,
Could you tell me who has the 44.68.52/24 subnet? I am the coordinator
for 44.68/16 (NY State) and I have not issued anything in that range.

It occurs to me that you'd get better results using a non-44
NTP service such as pool.ntp.org, as the traffic wouldn't have to
travel over your tunnel with its variable delays and congestion.
Likely it's a better stratum as well.
